A friend of mine is looking for map outline data. He needs state and county boundaries of Pennsylvania and New York. Rivers, towns, and other major features would also be a plus. Can anyone offer us a pointer to how to find such data. It will eventually end up being used internally by a company, probably printed by Ventura Publisher or something. EMAIL appreciated, since I don't usually read this (no doubt interesting 8-) group. thanks, lee

The USGS sells a very nice Optical CD ROM with all 50 states that includes counties, rivers, streams, water bodies, major roads and railroads. The disk seems to have about ~100 megs of data with I believe 3 different types of data files. A PC demo program will allow you to graphically look at the data you are interested in, and there is on-disk documentation for the file formats. I bought my disk for $28 from the USGS office in Menlo Park. You can also get the disk by calling the Reston, Virginia office: 800-USA-MAPS. The disk is called: 1:2,000,000 scale Digitial Line Graph (DLG) Data. Mark Zaller Air Venture, Palo Alto, CA Remote Sensing and Analysis

The Data User Services Division of the Bureau of the Census also has data on CD-ROM (TSO standard format) that is derived from USGS 1:100,000 map data and may be a bit more 'object oriented' than USGS files. Call (301) 763-4100 for more info or they have a BBS at (301) 763-1568. I have some old ancient census data that's fairly small (only a few meg) but is not in any standard coordinate system that I'm aware of and isn't much good for anything but drawing state outlines. --Hardy Pottinger, hjp@ee.umr.edu
